A 1980s filter chip that uses switched capacitors

Ken Shirriff's latest chip teardown examines the ML10, a 1980s integrated circuit that implements analog filtering using switched-capacitor techniques, replacing resistors with capacitors and switches on the die. The deep-dive traces the chip's internal circuitry and explains how switched-capacitor filters worked and why the approach mattered for analog signal processing.

Why now: Detailed hardware reverse-engineering posts by Shirriff reliably draw strong interest from the tech community, especially when they explain vintage semiconductor design techniques.
